Abstract

PURPOSE: To obtain the titled compound in high space time yield in high yield, by subjecting propylene, oxygen and ammonia to contact reaction in the presence of a specific improved catalyst at high temperature in gaseous phase.
CONSTITUTION: Propylene, oxygen and ammonia are subjected to contact reaction in the presence of a catalyst at high temperature in gaseous phase, to give acrylonitrile. In the reaction a composition shown by the formula Moa Teb Sbc Cod Pe Snf Og (a is 12; b is 0.1W5; c is 2W10; d is 2W10; e is 0.1W3; f is 0.5W3; g is 45W91) calcined at 550W800°C is used as the catalyst. Consequently, the yield of acrylonitrile is raised extremely at relatively low reaction temperature and for a relatively short contact time. The catalyst has good head stability and long catalytic life.
